[dpdk-stable] patch 'net/virtio-user: fix used ring in cvq handling' has been queued to LTS release 17.11.6

[Yongseok Koh <yskoh@mellanox.com>]

Hi,

FYI, your patch has been queued to LTS release 17.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objection by 03/13/19. So please
shout if anyone has objection.

Also note that after the patch there's a diff of the upstream commit vs the patch applied
to the branch. If the code is different (ie: not only metadata diffs), due for example to
a change in context or macro names, please double check it.

Thanks.

Yongseok

Subject: [PATCH] net/virtio-user: fix used ring in cvq handling

[ upstream commit 0403e37a468df59707ed938cca4a507276a0befb ]

When updating used ring, the id in used element should be the
index of the first desc in the desc chain.
